Status of this Memo
This document specifies an Internet standards track protocol for the
Internet community, and requests discussion and suggestions for
improvements. Please refer to the current edition of the "Internet
Official Protocol Standards" (STD 1) for the standardization state
and status of this protocol. Distribution of this memo is unlimited.

Abstract
This document specifies the set of RFCs comprising the Lightweight
Directory Access Protocol Version 3 (LDAPv3), and addresses the "IESG
Note" attached to RFCs 2251 through 2256.
1. Background and Motivation
The specification for the Lightweight Directory Access Protocol
version 3 (LDAPv3) nominally comprises eight RFCs which were issued
in two distinct subsets at separate times -- RFCs 2251 through 2256
first, then RFCs 2829 and 2830 following later.
RFC 2251 through 2256 do not mandate the implementation of any
satisfactory authentication mechanisms and hence were published with
an "IESG Note" discouraging implementation and deployment of LDAPv3
clients or servers implementing update functionality until a Proposed
Standard for mandatory authentication in LDAPv3 is published.
RFC 2829 was subsequently published in answer to the IESG Note.
The purpose of this document is to explicitly specify the set of RFCs
comprising LDAPv3, and formally address the IESG Note through
explicit inclusion of RFC 2829.

RFC 3377 LDAPv3: Technical Specification September 20022. Specification of LDAPv3
The Lightweight Directory Access Protocol version 3 (LDAPv3) is
specified by this set of nine RFCs:
[RFC2251] Lightweight Directory Access Protocol (v3) [the
specification of the LDAP on-the-wire protocol]
[RFC2252] Lightweight Directory Access Protocol (v3): Attribute
Syntax Definitions
[RFC2253] Lightweight Directory Access Protocol (v3): UTF-8
String Representation of Distinguished Names
[RFC2254] The String Representation of LDAP Search Filters
[RFC2255] The LDAP URL Format
[RFC2256] A Summary of the X.500(96) User Schema for use with
LDAPv3
[RFC2829] Authentication Methods for LDAP
[RFC2830] Lightweight Directory Access Protocol (v3): Extension
for Transport Layer Security
And, this document (RFC3377).
The term "LDAPv3" is often used informally to refer to the protocol
specified by the above set of RFCs, or subsets thereof. However, the
LDAPv3 protocol suite, as defined here, should be formally identified
in other documents by a normative reference to this document.
3. Addressing the "IESG Note" in RFCs 2251 through 2256
The IESG approved publishing RFCs 2251 through 2256 with an attendant
IESG Note included in each document. The Note begins with:
This document describes a directory access protocol that provides
both read and update access. Update access requires secure
authentication, but this document does not mandate implementation
of any satisfactory authentication mechanisms.
